have difficulties transitioning to a nuclear family are attracted to the Evergreen model despite the controversy, because it legitimises and reanimates the same ideas about family and domesticity as does the adoption process itself, offering renewed hope of "normal" family life. Institutionalized or abused children often do not conform to adopters conceptualizations of family behaviours and roles. The Evergreen model pathologizes the child's behaviour by a medical diagnosis, thus legitimising the family. As well as the promise of working where traditional therapies fail, attachment therapy also offers the idea of attachment as a negotiable social contract that can be enforced in order to convert the unsatisfactory adoptee into the "emotional asset" the family requires. By the use of confrontation the model offers the means to condition children to comply with parental expectations. Where the therapy fails to achieve this the fault is attributed to the child's conscious choice to not be a family member, or the child's inability to perform as family material. Contrasting mainstream position Within mainstream practice, disorders of attachment are classified in DSM-5 and ICD-10 as reactive attachment disorder (generally known as RAD), and Disinhibited social engagement disorder. Both classification systems warn against automatic diagnosis based on abuse or neglect. Many symptoms are present in a variety of other more common and more easily treatable disorders. There is as yet no other accepted definition of attachment disorders. According to the American Academy of Child and Adolescent Psychiatry (AACAP) practice parameter published in 2005, the question of whether attachment disorders can be reliably diagnosed in older children and adults has not been resolved. Attachment behaviors used for the diagnosis of RAD change markedly with development and defining analogous behaviors in older children is difficult. There are no substantially validated measures of attachment in middle childhood or early adolescence. Prevalence Attachment therapy prospered during the 1980s and 1990s as a consequence of both the influx of older adopted orphans from Eastern European and third world countries and the inclusion of reactive attachment disorder in the 1980 Diagnostic and Statistical Manual of Mental Disorders which attachment therapists adopted as an alternative name for their existing unvalidated diagnosis of attachment disorder. According to the APSAC Task Force, these therapies are sufficiently prevalent to have prompted position statements or specific prohibitions against using coercion or restraint as a treatment by mainstream professional societies such as: American Psychological Association (Division on Child Maltreatment),
